BOILER.

Specification of Letters Patent.

Patented Oct. 27, 1914.

Application filed January 5, 1914. Serial No. 810,326.

To all whom it may concern:

Be it known that I, LEOPOLD R. Hinson, a citizen of the United States of America, residing aty Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Boilers, of `which the following is a specification. a

My invention'relates generally to boilers, and has especial reference to wash boilers wherein clothes and like .articles may be boiled, to dispense with the necessity of subjecting the same to any other cleaning action. i The principal vobject of my invention is to provide a boiler of simple construction wherein a circulation of water is maintained, the water being freed from its contained impurities in the course of circulation.

A further object is to `provide means, in a boiler of this kind, to prevent the boiling water from overiiowing when the cover is raised while the boiler is still on the lire. Other objects and advantages of the invention, and its detail structure and operation will be fully explained in the following specification.

The preferred embodiment of the invention is illustratively exemplified in the accompanying drawing, wherein- Figure 1 is a substantially central, vertical sectional, view of a boiler provided with my invention; and Fig.' 2 is a horizontal sectional view on the line 2 2 of Fig. 1.

Referring to the drawing by reference characters, 10 denotes the body of the boiler, having the bottom 11, and above the latter the false bottom 12. Boilers of this type are usually elliptical, and the boiler is so shown in the drawing.

Within the boiler 10 near one end thereof, is a perforated pipe 13, having its upper end closed, and its lower end open and communicating with the space 14 between the true bottom 11 and the false bottom 12. The pipe 13 extends about half the height of the boiler and is suitably secured in position, as by a bracket 15.

At the end of the boiler opposite that in which the pipe 13 is arranged, is an imperforate pipe 16 open at bothv ends, the lower end communicating with the space 14, and the upper end being almost flush with the upper edge of the boiler body 10. The pipe 16 is secured in position within the boiler by a bracket 17 or other appropriate means.

The upper edge 10a of the boiler body is preferably curled as shown in Fig. 1, and is adapted to support a fairly shallow tray 13 the base of which is provided with a plurality of perforations 19. Resting within the tray 18 on the upper surface of the perforated base is a body of filtering material lar material. The tray is formed with a suitable orifice to tightly embrace the pipe 16, which projects through the tray.

The boiler cover is designated 21, and has a depending flange 22 designed to engage the preferably curled, upper edge 18a of the tray 18.

Arranged to operate within the tube 13 isl a suitablyv constructed iioat'valve, in the present case consisting of the conical valve proper 23, connected by the rod 24 tothe float body 25.

To prevent overflow of boiling water when the cover 21 is raised from the boiler I provide the following arrangement Pivoted to a bracket 26 depending from the under surface of the false bottom v12 is a double armed lever 27, one end of which is provided with an orificed, substantial plate 28 designed to receive the valve 23 and the other end of which is provided with or shaped as a disk 34 and has attached thereto a socket 29 into which one end of a rod v30 extends. The rod 30 passes up through the pipe 16 and is steadied therein `by a suitable guide 31.

The operation of the boiler above described is asfollowsz-The boiler is nearly lled with water and then placed on a fire. The clothes to be cleaned may be placed in the boiler before or after the water boils. When the lid 21 is placed on the boiler, the projection 32 on the under face of the lid will encounter the upper end of rod 30 depressing the latter and causing the lever 27 to rock about its pivot into the position shown in Fig. 1 in full lines. The water in boiler 10 will pass through the perforations in pipe 13 (unseating the valve 23), pass through the space 14, up through the pipe 16 and into the tray 18. The filtering pad in the tray will free the water from its contained impurities, and the filtered water willA pass through the perforations 19 in the tray onto the clothes within the space 33 in the boiler. The circulation of boiling water icc 65 20, such as a substantial pad of felt or simiy assume the reverse position from that indicated in Fig. 1, and when the parts are in this position no Water passes .up through pipe 16, thus preventing overlioW. rlihe only path that any Water in the space 1li can take is through the perforated tube 13 back into the body of boiler 10.

The upward flow o- Waterthrough the pipe 16 is iirstcaused by the excess pressure in boiler 10 and space 111, andvvhen the circulation is started a suction action in pipe 16 seems to occur, Which accelerates such circulation and makes it very rapid. VIlChis forced circulation enhances the cleaning action of the water on the clothes'.

Having thus described my invention, what l claim is `1. A boiler, embodying therein a boiler body provided with a Water space, oppositely disposed pipes for maintaining Water circulation in said boiler, a cover for the latter, and means operating automatically to prevent overflow from the boiler when said cover, is raised.

2.` A boiler, embodying therein a boiler body provided With a Water space in its base, a perforated ltering tray suspended from the upper part of vsaid body opposite said water space, and oppositely disposed pipes for maintaining Water circulation, one of said pipes being longer than the other and opening into said Water space and said filtering tray.

3. A boiler, embodying therein a vboiler body provided With a Water space in its base, a perforated'ltering tray suspended in said body .trom the upper edge of said boiler, a perforated pipe closed at one end and having its opposite end opening into said Water space, an imperiorate pipe. open at both ends and communieatingI kwith both the Water space and the filtering tray, and automatically operating means to prevent overlowof Water when the boiler cover is raised.

11. A boiler, embodying therein a 'boiler body provided with a Water space in its` base, iltering means depending Within the boiler near the upper edge thereof, a perforated pipe near one end of lthe boiler said perforated pipe having one end in open communication with said Water space and its other end closedand an imperforate pipe opposite said perforated pipe, said imperforate pipe being open at both ends and communicating, respectively, With said Water space andsaid filtering means.
